it cannot express upstream's `wac`-composed multi-component tests (runner -> intermediate -> leaf) or the core/ component `.wat` demo. Drop common-types, resource_floats, resource-import-and-export, resources, resource_with_lists, results and demo. Their type coverage (records/variants/results/resources) is retained by flavorful and the resource_* tests.

runtime tests that need unimplemented features These tests exercise wit-bindgen Rust *codegen* knobs or multi-component structures the wRPC generator/harness intentionally does not support, so they cannot run as transport tests without unrelated generator work: - unsupported generator flags: disable-custom-section-link-helpers, method-chaining (--enable-method-chaining), ownership (--ownership), raw-strings (--raw-strings/--std-feature), run-ctors-once-workaround (--disable-run-ctors-once-workaround) - wac multi-component / multi-world: equal-types (also --merge-structurally-equal-types), two-wit-packages, with-only-affects-imports, xcrate - other-dependencies: two packages in one directory, which the single-package runtime-test loader cannot parse Assisted-by:

A WIT type whose upper-camel name is `C` (e.g. a type/variant named `c`) then resolved to the generic parameter instead of the type, breaking `Encode`/`Decode`. Rename the generic to `C__`; generated WIT type names never contain underscores, so it cannot collide (matching the existing `wrpc__`/`cx__` parameter-naming convention). Restore the with-types runtime test to use the natural `c` type name it previously had to rename to dodge this bug.

When the flag count is a multiple of 8 the final byte is fully used, so the shift was 0 and every legitimately-set bit in that byte was rejected with "bit not associated with any flag is set". Shift by the number of meaningful bits in the last byte (`(len-1) % 8 + 1`) instead, which is 8 for byte-aligned counts.
